Determining Whether a Point Lies on a Circle
A circle centered at the origin contains the point
(0, -9). Does (8,717) also lie on the circle? Explain.
EEO

No, the distance from the center to the point
(8, 17) is not the same as the radius,
No, the radius of 10 units is different from the
distance from the center to the point
(8,717)

Answer:

No

Step-by-step explanation:

If the center is at (0, 0) and if (0, -9) lies on the circle, then the radius must be 9.

In this case, the equation of this circle is

x^2 + y^2 = r^2 = 9^2.

Does (8, 717) satisfy this equation?  No.  717^2 would be far outside of the circle.  the distance from the center to the point  (8, 17) is not the same as the radius

Answer:

Yes, the distance from the origin to the point  

(8, ) is 9 units.
